실험 절차

4-[4-(1,3-Dioxo-1,3-dihydroisoindol-2-yl)butyl]benzenesulfonyl chloride 13 (0.45 g, 1.19 mmol) was dissolved in dry DMF (5 mL), and added to a solution of N-methylmorpholine (3 mL) and (2S)-amino-3-methylbutyramide (0.18 g, 1.19 mmol) in DMF (10 mL). The reaction mixture was stirred at room temperature for 66 h. Solvent was removed by rotary evaporation and the residue was purified by flash silica gel chromatography eluting with chloroform/methanol/concentrated ammonium hydroxide (15:1:0.1, v/v) to give the desired product 14 as a white powder (0.41 g, 73% yield). 1H NMR (300 MHz, DMSO-d6) δ 0.72 (d, 3H), 0.76 (d, 3H), 1.77 (m, 4H), 1.79 (m, 1H), 2.68 (m, 2H), 3.40 (m, 1H), 3.60 (m, 2H), 6.92 (s, 1H), 7.21 (s, 1H), 7.34 (d, 2H) 7.50 (d, 1H), 7.65 (d, 2H), 7.82 (m, 4H).
